DAVID HYHAN, OF HARRISBURG, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO JOSHUA W. JONES, OF SAME PLACE.

GLOBE-FRAME.

SPECIFICATION forming part of Letters Patent No. 411,443, dated September 24, 18189. Application filed July 26, 1888. Serial No. 281,157. (No model.)

1'0 all whom, it may concern:

Be it known that I, DAVID HYMAN, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of 5 Pennsylvania, have invented an Improvement in Globe-Frames, of which the following is a clear, full, and exact specification, which will enable skillful artizans to construct and use the same.

My invention relates to appliances adapted for electric lights, especially suited for use on electric-arc lights Whether the same are hung in the open air, as in streets and parks, or in inclosed places in'buildin gs, it being applicable to almost all electric-lightsystems where globes are now used.

The object of my invention is to furnish a substitute for the globe now in use and which can be placed in a small and safe package,

and thus obviate to a great degree the objections that now exist against the shipment of globes. In making this substitute for globes several points must be taken in considera tion to overcome many objections that would be raised to its use. It is well known that any opaque body interposed between the light and the place to be illuminated will cast an intensely black shadow. To overcome this the sides of the lantern are made of sections of glass which abut against each other at the edges, so that the corners will transmit light, which is not the case with lanterns having the edges of the sides sect-ions joined together by metal strips, as is the case with 3 5 ordinary street gas-lamps. These sections are loosely held at top and bottom to permit of expansion due to the intense heat of the arc lamp and contraction which takes place when the light is put out. Another feature is that the sides can be easily replaced by the ordinary street-1i ghtadj usterif one or more should be broken, whereas a globe if broken must be replaced by a new one. To hold the sections at top and bottom suitable top and bottom pieces are used and are connected together by rods of very small diameter, which are located near the points where the edges of the glass meet, so that the reflection from the abutting edges will overcome the shadow which would otherwise be cast by the rods. Moreover, the lantern may be with or with out bottom and may have one or more of its sides adapted as light-reflectors whether plain or curved and whether the sides are of glass or metal or of both kinds combined. My preferred construction of lantern con- .sists of a basal spider formed of a central hub and radial arms having grooved palms at the perimeter of the arms for retaining thereon the lantern-sides by holds therefor in said grooves at the polygonal angles of the lan tern, and having interior flanges on said arms for retaining thereon sections of the removable bottom of lantern, and the top of said frame is a sheet-metal disk formed with exterior lips bent down for embracing the lantern-sides eXteriorly, and also formed with interior tangs struck from the said disk and bent down suitably for embracing said lantern-sides by bearing against their insides 7o adjustably, the central part of said disk having an aperture suitable to admit freely jtherethrough the rods of the electric-light supports. Vertical bolts connect said top plate with the palms near the perimeter of The mechanism for ob- Figure 1 is an isometrical perspective view of my lantern detached from the holder. Fig.

2 represents a vertical section of the lanterntop, taken through the middle of the opposite sides thereof; Fig. 3, the basal frame or spider .at base of lantern in plan; Fig. 4, a cross-section of same, taken on the indicated line B R Fig. 5, a plan View of one of the similar sections of the lantern-bottom; Fig. 6, a cross- 0 section of one of the radial arms of said bottom frame, taken at the line of the wire or pin, securing thereon the bottom sections; Fig. 7, a vertical section of my said lantern or globe frame, with an electric-arc light illus- 5 trated in position therein.

Similar letters refer to similar parts throughout the several views and descriptions.

The spider or basal frame A a H consists of the hub H, in which is a socket K for attach- I03 ing the spider to a part of the carbon-holder abutted thereto by set-screw or set-screws,

and of the diagonally-extended arms A, which have upon theirouter ends the angular palms n, which latter are provided with the grooves n on top thereof between the ledges M and palm n, and said arms are provided with inwardly-slanting flanges a,-skirting them and the hub H alike, all being in form and location as shown in Figs. 1 and G. The palm n is shown wedged shape, and forms with the raised part of the arms a recess or angle 71 for one of the corners of the bottom glasses. Vertically above said basal frame is the correspondinglyangled top plate Q, provided with the downturned exterior flanges 7c, and with the tangs G struck from the sheet that forms the top, and also turned down to stand parallel to and near the adjacent exterior flanges, as shown in Figs. 1 and 2. Said flanges are arranged to be parallel to the ledges M on basal frame, and they bear alike against the glass faces or sides S in the corresponding vertical plane, and said tangs are arranged to bear against the insides of said faces of lantern yieldingly to compensate for different thicknesses thereof. Said tan gs may 0 bent back to the plane from which they were struck up, and thus allow the lanternside to be removed without undoing the screwbolts N, which latter are formed with thumbbuttons above and with screw-threaded points below, and work in tapped holesT in the arms A, or may be provided with nuts below the arms A. The aperture P in the top plate, to admit therethrough the rods which support the electric-light holder, affords approach to reach the sides S by the unaided hand when they are to be removed, as when cracked or broken. The grooves in said palms are amply deep and wide to admit therein, along with a pane of glass, also a burnished or polished sheet of metal or metallic pane when said sides of lantern are to be converted into a reflector, as when the light would otherwise fall upon a blank wall. Said grooves n also admit therein cuttings of sheet-rubber interposed between the palms and the basal margin or edges of the face S, to relieve the set of the latter on the basal frame and to prevent rattle by gusts of wind.

Upon the interior flanges a on the arms A, hub H, and palm n are supported the sections Z, preferably of glass, to form a trans parent bottom of lantern. Said sections extend outwardly a little farther than the outside of the lantern-faces S, that the latter may bar the vertical displacement of said sections, yet permit their removal, when a cotter-pin C or a soft Wire V, inserted through the opening in projection W of the arms A, and bearing on said section of bottom, is also removed.

The lateral displacement of the sections Z is prevented by the arms A, against which their edges abut, and by the downward slanting ofthe ledges on the arms on which the plates or sections Z are supported, thus gravitatin g toward the hub H of said basal frame.

The ledges a are a little lower than the the top plate.

grooves n, and therefore the lower edges of the sides S may rest on said bottom sections; and said ledges being slanted centerward and downward. any particles from the spent carbons will be conveyed to and be collected about the hub H, thus preventing the emission of live particles from the lantern in houses, where safety is a requisite against fire.

In outdoor situations the bottom of lantern may be omitted where the destruction of insects may be desirable by admitting them directly to the fire of the light and when singed let-ting them drop out below. In many instances, therefore, the lantern will not need to be removed, as the carbons may be replaced and adjusted by reaching them below through the openingof lantern-frame.

InFig. 3 is shown the set-screw L on hub of the basal frame, for attaching the hub to a shank of certain forms of holders that may be inserted in the eye K. In other cases or forms of holders said set-screw may be omitted, as a bottom nut, usually on said shank, or other means maybe utilized for attaching the lantern removably to the light-holders.

Although a rectangular form of lantern has been selected to illustrate my invention, it is clear that a hexagonal, octagonal, or other polygonal form may be adopted by adopting the same principlesof construction, it being necessary to vary the angles defining the grooves or supports of the sides and the corresponding flanges or tangs depending from It is also clear that sections of cylinders may take the places of plane sides if the retaining-grooves be made semicircular and the top-plate flanges be modified accordingly. In either form a portion of the lantern side or sides may be converted into reflector-surface, where the brilliancy of light would not be desirable or where its benefit would not be fully utilized.

I claim 1. A lantern for are electric lights, consisting of a basal frame or spider having central hub provided with an eye for attaching the lantern to the shank of the lower carbon holder by a screw, said hub having radial arms provided with grooves adapted to sustain therein the bottom edges of panes of glass, as the lantern-sides, a top plate having devices for securing the upper edges of the panes, and wire rods inserted through the top plate and through the spiders arms, the wire rods having heads beneath and screw-nuts at upper end for connecting the plates squarely, all combined and arranged about the electric light, substantially as set forth.
